Dude it says needs battery and nothing about it being spares or repairs or it may or may not work.
So if it arrives and it don't work with new batteries the buyer has redress via ebay.
I know I've done it myself.
Recently I bought a Hammy from the US I asked them to put on the paperwork "broken watch for repair"
The seller sent me a nasty email saying he wouldn't as it wasn't a broken watch.
When it arrived and it didn't work with a new battery, along with the fact the lid on the plastic box
had been broken, as he had only packed it in one layer of bubble wrap then taped it up in a padded bag.
I sent him photo's, and he gave me a full refund. As he said if he didn't ebay would, and then take it from
him anyway. Because he had said it wasn't broken, and that was only in a message after the purchase,
and not in the listing.
I also got my own back on a "don't know if it works no batteries to try it" type of listing. I wasn't really
bothered as I was buying it for other bits, band etc.
When it turned up I made a video of me opening the package as I always do just in case they send me
a bag of crap/not the item I bought. I carried on filming when the back came off the watch and the
batteries fell out. First thing I did was check them (still filming) and low and behold 1.57 volts. Hmmmm
Sent him a message and some pics from the film to back it up, which he ignored.
Opened a case which he responded saying "I was lying". I just said I had proof, and contacted ebay.
Money was in my account within 10 minutes. # smugface
And the moral of the story is,,, DON'T LIE..
